What is the domain for the following function?

Mathematics
1 answer:
sammy [17]4 years ago
3 0

Answer:

it's B

Step-by-step explanation:

the set of numbers for which a function is defined is called a domain of a function

if a number is not in the domain of a function, then the function is undefined for that number

denominator must not be zero

if we plug -3 then the y

=(-3+1)/(9+-3-6)

=(-2)/9-9

=-2/0

which is undefined for x=-3

now

if we plug 2 we have

(2+1)/(4+2-6)

=3/0

the function is undefined for x=2

so

x≠3, x≠2

Calculate the volume of the cylinder, where a = 18 and b = 11. Use 3.14 for pi and round your answer to the nearest tenth.
cupoosta [38]

Answer:

Volume of cylinder =2797.7

Step-by-step explanation:

Let a be diameter and b the height of the cylinder

Then\ radius(r)=\frac{diamater\ (a)}{2}\\\\r=\frac{18}{2}\\\\r=9

Volume of cylinder =\pi\times(radius)^2\times(height)

=\pi\times(9)^2\times11\ \ \ \ \ \ (\pi=3.14)\\\\=3.14\times9\times9\times11\\\\=2797.74\\\\\approx2797.7

PLEASE SOMEONE WHO IS SMART ANSWER THIS QUESTION
Daniel [21]

Answer:

36/32 or 1 1/8 (same thing)

Step-by-step explanation:

9 gallon / 32 quarts

First, you have to convert 9 gallon to quarts to match the denominator. In the table, it says that 1 gallon = 4 quarts, so you have to do, 9 x 4 which gives you 36. Now that the fraction is in the same form of units, 36 quarts / 32 quarts, you will have to write it as a mix fraction or you can just leave it as 36 quarts / 32 quarts. If you want it in mix fraction, it is 1 1/8.

Find the value of each angle mentioned above.​
nataly862011 [7]

Answer:

36°, 42°, 72°, 102°, 108°

Step-by-step explanation:

Angles at a point = 360°

Therefore:

(3x - 6) + x + 3x + 2x + (x + 6) = 360°

Open parthenogenesis

3x - 6 + x + 3x + 2x + x + 6 = 360

Add like terms

10x = 360

Divide both sides by 10

x = 36

✔️Value of each angle:

Plug in the value of x in each expression

x = 36°

3x - 6 = 3(36) - 6 = 102°

3x = 3(36) = 108°

x + 6 = 36 + 6 = 42°

2x = 2(36) = 72°
